81466c3768 1) Fixed XCP_MESSAGE_LENGTH to represent the real max length. We have the column defined as VARCHAR(1023), so there's no need to subtract the overhead. 
2) Slightly refactored the message buffer management.
3) Fixed the buffer overrun in the release build.

fc12495d0e Modified IStatement interface in our API: 
1. Never allocate empty statement - always use att->prepare() to create statement interface
2. Separated IStatement into 2 parts - statement itself and resultset.
3. Added stmt->openCursor() (and att->openCursor() for unprepared statements) to create IResultSet.
4. Always use IMessageMetadata (former IParametersMetadata) to pass message fromat info from client,
   therefore avoiding need in BLR generation in client applications.

513ce5e1ce Additional patch for improvement CORE-3362 : Cursors should ignore changes made by the same statement. 
- SubQueryNode (sub-select's) and RseBoolNode (exists(), in\any\all) now knows if it is a part of some outer select (ForNode) or it is a standalone statement. 
- VIO\get_undo_data was reworked to better fit undo-log implementation, corresponding changes in VIO_chase_record_version also done
- AV in VIO\get_undo_data was fixed

70d5ebdfdf - Got rid of the fixed array that kept the stream count in the first element and 255 streams after it. 
- Changed streams from UCHAR to ULONG as Dmitry wanted
- Got rid of some redundant flags to indicate BLR level
- Misc changes (for example, converted to test for DBB_read_only in Database to a function)
- BLR v6 is left commented (waiting for a better solution to appear, if any exists)
- This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.

c627005a89 Feature CORE-3626 - Subfunctions in PSQL and EXECUTE BLOCK. 
Tests at http://firebird.cvs.sourceforge.net/viewvc/firebird/fbtcs/GTCS/tests/FB_SQL_SUBFUNC_1.output.

Also did:
- Refactor to share more code/data between procedures and functions.
- Fixed some PSQL functions problems.

5ae632cf0b Feature CORE-1288 - Sub Procedures. 
They're very simple for now. No access to parent variables nor to call neighbour procedures.

Tests at http://firebird.cvs.sourceforge.net/viewvc/firebird/fbtcs/GTCS/tests/FB_SQL_SUBPROC_1.output.

a3064848d6 Make ExprNodes and RecordSourceNodes reference others directly instead of via jrd_nod. 
Store ValueExprNodes instead of jrd_nod in the metadata cache.
Make RecordSourceNode child of ExprNode as they share most operations.
Get rid of the JRD visitors in favor of direct calls.
Convert assignments statement lists created inside expressions to separate source and targets ValuesExprNodes.

9b8171d5c1 1) Refactor nod_value_if. 
2) Created ExprNode::expressionEqual method to replace a new big and ugly switch.
3) Make boolean referencers use BoolExprNode instead of jrd_nod, except nod_validate for now. This includes BinaryBoolNode and NotBoolNode working without jrd_nod references.
4) Rework in the impure allocation code (replace "csb_impure += ..." by CMP_impure calls).
